What the Diepsloot climate table shows
Values are multi-decadal climatological averages for the -25.93312, 28.01213 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Does Diepsloot get the same every year?
